See how one of them has an ID of 7? That's the Windows partition. Note which device it's on (in this case, /dev/sda1.)
Now type ls /media and note the exact spelling of the Windows folder. (In my case, "Windows XP Professional")

Go to your Terminal and typesudo mount -t ntfs -r nls=utf8,umask=0222 /dev/sda1 "/media/Windows XP Professional"EXCEPT replace /dev/sda1 with the device you noted earlier, and "/media/Windows XP Professional" with /media + the folder name you noted earlier. (Be sure to include the quotation marks, especially if the name has spaces in it.)

If you get any errors, type sudo umount /dev/sda1 (or whatever location you found eralier,) and then try again.
If you decide to try it yourself, and can't fix an error, please tell me, and include the error that the Terminal gives you. (To define code in a comment, surround it with these: `)
